It’s more than that. Those colors were chosen to hide the ever-present, persistent glaze of nicotine stain over everything. There were no white walls back then, only shades of “cream”, “ecru”, and “off-white” because no shade of true white could exist in that persistent haze of cigarette smoke.

If you ever took over a house from the 70s you’d note the amber brown drips down the kitchen wall after making spaghetti or heating a tradition tea kettle on the stove. Or after a shower in the bathroom. Scrubbing, priming, and painting would help, and then you’d make another pot of spaghetti and see another amber sludge nicotine drip from somewhere on that wall.

To this day I cannot abide beige, any rendition of off-white, or pale yellow. They’re all shades on the nicotine glaze color palette.
